Did anything ever come of the guy working on an STM port of RRF?

The port for stm32f4 in is almost ready, and successfully works on several printers, but still there are some bugs, besides it is necessary to clean up the code. By the end of the month, I'll post it on github and send a link. I planned to finish it earlier, but I don't have enough free time

question about the ESP-Wifi integration:
Is the ESP unit working as a bridge to communicate to the network or is it working as an integrated piece of hardware with the LPC processor?
What if any code runs on the ESP unit?
Perhaps I misunderstand, do we need both Ethernet AND Wifi modules compiled in to the FW?

sdavi -
thanks for explaining it so well. I have forgotten so much of this since college.
1. so by moving the tcp/ip stack off the LPC,does it gain us any more memory to the system as well? is this desirable to do anyhow?
2. what pins does the esp/wifi unit need to work? will it free up more pins on the LPC boards then?
3. can you compare performance overall between Eth0 and Wifi? is it measurable really?
4. Is DWC then running on the ESP or on the main CPU?
You are really making it hard not to migrate to RRF3!

Given that it does not seem currently possible to operate both the display and WiFi (due to memory I think), this is probably not a big deal.
The WIFI is also running as a SPI Master.

Ah yes but I was thinking that for some boards (like some of the SKR boards) that do not use the hardware SPI to drive the LCD it might be possible to still operate the display (but no external SD card reader) at the same time as using the WiFi, but memory may be the bigger problem.
I'd actually rather like to be able to have a minimal LCD menu system (just the main status screen, with perhaps the ability to pause/abort a job), if it was possible to fit it all it. That way I could have a local display on the printer that showed basic status. But I suspect that memory is just going to get tighter as RepRap V3.1 etc. comes out.

i miss that having switched to LPC port. It would give the state, the temps, percent complete and time estimate.

dc42: are you saying that the LPC subsystem is already spitting out the datastream ?
what I was refering to was an LCD connected to the raspi. the data stream parsed by Octoprint and processed through the raspi/GPIO pins to a 4 line 20x4 HD44780 display.
[github.com]
there was another one that did it with I2C -
[plugins.octoprint.org]
see in my pic that the 12864 is connected to the RAMPs? the 20x4 is connected to the pi3B+.

sure, that works!
but the thing is you need some sort of device to parse it and direct it to a display.
Since I longer use the raspi with RRF, what is missing is the computer to process the M408 data and a means to display it.
I am curious how you are parsing the M408 data and how far back a data stream you archive
